Design and implementation of a simulator for the analysis of bit error rates by using orthogonal Frequency Division Multiplexing

Orthogonal Frequency Division Multiplexing (OFDM) has become very popular for its advantages. The researches are till going on for the development of OFDM. In this paper we have described a new simulator that can perform the BER analysis using OFDM technology and generate respective plots for bit errors vs signal energy (Eb/No) for several modulation schemes & different noise effects in three types of channels (namely AWGN, Rayleigh and Rician).
